Check Pump Operation/Pump Release; Checking The Condensate Drain Pipe; Instructing The User - Biasi RIVA PLUS HE 24C ERP User Manual And Installation Instructions

7.12 Check pump operation/pump
release
The pump electronic control circuit automati-
cally releases the pump.
Connect the boiler to the mains .
Make sure that the ambient thermostat is in
the "heat demand" position.
Check that the boiler with the gas cock shut-
off goes into ignition lockout (Er01) and, in the
meantime, check the pump release.
The pump release can be verified by checking
that the pump motor vibrates.
If the pump motor does not vibrate, release
the boiler from its lockout due to gas failure
by pressing the reset button on the control
panel and repeat the sequence a maximum of
10 times.
If the pump does not release, contact technical
support.
Once the pump has been released, open the
gas cock and check that the boiler operates
correctly both in domestic hot water and heat-
ing modes.

drain pipe
Check the soundness and integrity of the
condensate drain pipe.
Verify the cleanness and correct filling of the
